VENTlLATlNG ATTACHMENT FOR wmoows.

SPECIFICATION forming part of Letters Patent No. 606,088, dated June 21, 1898.

Application filed March l, 1897. Serial No. 625,482. (No model.)

To all whom it may concern.-

Be it known that l, KAREN CHRISTINE SAN- BORN, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Ventilating Attachment for Windows, of which the following is a full, clear, and exact description.

The object of the invention is to provide a ventilating attachment for windows whereby the lower sash may be given an inclination within the room, the space between the inclined window-sash and the window-frame being thoroughly protected against the entrance of insects, while the inclination of the lower sash will be such as to preclude the entrance of rain into the room, thus permitting of thorough ventilation of the room even in inclement weather.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Referenceis to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a windowframe and its sashes, the improvement being applied to the lower sash and the lower sash having a corner broken away. Fig. 2 is a vertical section taken substantially on the line 2 2 of Fig. 1, and Fig. 3 is a horizontal section taken practically on the line 3 3 of Fig. l. i

The window-frame A may be of the usual construction, and the upper sash B and the lower .sash B are mounted to slide therein in the customary way; but the inner stop-beads 11 of the window-frame, instead of being nailed to the frame or equivalently fastened, are connected to said frame through the medium of hinges 12, as shown particularly in Figs. 2 and 3, whereby the inner stop-beads may be carried parallel with the inner vertical faces of the sides of the window-frame, thus admitting of the lower sash B being carried within the room and given the upward inward inclination illustrated in Fig. 2.

The ventilating attachment consists of two side frames (3 and a top frame O. The side frames are interposed between the inner faces 'of the window-frame and the outer faces of the side rails of the lower window sash. Therefore the side frames Care of angular construction, having substantially the form ofv a right-angled triangle. O will consist of a straight outer upright bar 13, adapted to engage with the inner face of the Window-sash, an inclined inner side bar 14, which engages with the outer face of the side rails of the lower sash B, and a double top bar 15, the frame thus constructed being provided with a covering 16, of wire-netting, mosquito-netting, or the equivalents thereof. Each side frame 0 is provided with an extension 14, projected from the inclined side bar 14 a sufficient distance to enable a latch 17, of any desired character, attached to the extension, being passed over and made to engage with the upper surface of the top rail of the lower window-sash, as shown in Figs. 1 and 2. construction, the skeleton frame 18 whereof is covered, preferably, at the top and at the bottom with a perforated or reticulated material 19, and it may here be remarked that both sides of the ventilating side frames 0 are also covered with a reticulated or perforated material of the character described. Under such a construction it is obvious that no matter how fiercely it may rain the rain will strike on the inclined surface of the lower sash and will be conducted to the bottom of the window-frame, not entering the room,

"While at the same time ample ventilation is afforded and at a minimum of expense, the ventilating attachment being applied with little difficulty to any window Whose lower sash may be-given the desired inward inclination.

' The upper ventilating-frame O rests upon Each side frame The top frame 0' is of rectangular in this manner be as securely locked when the ventilating attachment is used as who the attachment is removed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a-window-frame provided with stop-beads hinged to the inner edge of the frame and adapted to be carried parallel with the inner vertical faces of the sides of the window-frame, and a lower sash held to slide in said frame and adapted to rest with its lower edge on the lower part of the said window-frame, the said sash being arranged to be given an inward inclination when the stop-beads are swung inward on their hinges, of a removable ventilating attachinent comprising a framework covered with a reticulated or perforated material and shaped to fit between the inclined lower sash and the window-frame, and locking devices whereby the ventilating attachment may be secured to the sashes, substantially as described.

2. The combination with a window-frame provided with inner stop beads having a hinged connection with the window-frame at the inner edge thereof, whereby said stopbeads may be carried parallel with the inner vertical faces of the sides of the windowframe, and a lowersliding sash for said Wl]1(l0\ frame having its lower edge adapted to rest in a groove in the lower part of the windowframe, the said lower sash being arranged when in its lowermost position to be given an inward inclination when the inner stop-beads are swung inward out of the way, of a ventilating attachment for the said lower sash consisting of ventilating side frames covered with a reticulated or perforated material and shaped to approximate a right-angled triangle, the straight sides of the frames being arranged for engagement with the face of the window-frame and the inclined sides with the outer face of the lower sash when the latter is inclined from the window-frame, a cover ventilating-frame arranged to rest upon the side ventilating frames and also provided with a reticulated or perforated covering, the inclined sides of the ventilating-frame being each provided with an extension at its upper part, and latches attached to the extensions and adapted to engage with the lower sash, substantially as set forth.
